This branch makes it possible to enforce convergence on residual and convergence on solution at the same time. Currently the condition for convergence requires either convergence on residual, or convergence on solution. Now, with this stronger condition of convergence, usually extra iterations are required to fulfil also the convergence on solution, if enabled.
